Methods and apparatus for sensing light output and controlling light output |
摘要 |
Methods and apparatus for lighting control. In some embodiments methods and apparatus are provided that sense a low lighting condition at a location and direct light toward that location after detection of the low lighting condition. In some embodiments apparatus are provided that include a plurality of networked LEDs (20, 30, 220, 230, 320, 330, 420, 430, 520, 530). Some of the LEDs may be illuminated in response to sensed light conditions at certain locations. |

1. A method of directing light toward a light-sensing surface, comprising:
associating a first sensor of a light-sensing surface with at least one of a plurality of light-generating LEDs; associating a second sensor of said light-sensing surface with at least one of said plurality of light-generating LEDs; monitoring a first sensor light intensity of said first sensor and a second sensor light intensity of said second sensor; detecting a first sensor blocked condition at said first sensor when said first sensor light intensity is below a first sensor threshold level; generating a first light output from at least one of said light-generating LEDs associated with said first sensor when said first sensor is in said first sensor blocked condition; detecting a second sensor blocked condition at said second sensor when said second sensor light intensity is below a second sensor threshold level; and generating a second light output from at least one of said light-generating LEDs associated with said second sensor when said second sensor is in said second sensor blocked condition. |
